Non-standard steel wheel casters — 4-inch, 5-inch, 8-inch, 10-inch diameters. For specialty containers and oversized heavy-duty dumpster applications.
Most steel-caster commercial applications use the 6-inch standard. The non-standard sizes serve specialty containers (smaller industrial bins, vault waste) and oversized heavy commercial dumpsters where extra ground clearance matters.
PRT stocks these sizes for specialty applications.
Match by load rating, wheel diameter, mount type (bolt-on or weld-on), and caster type (swivel or rigid).
Send PRT a photo of your existing caster with the container model number and we'll confirm fitment.
Smaller industrial bins, vault waste, or larger 6-8 yard heavy commercial dumpsters where 6-inch ground clearance is insufficient.
20-50% more than 6-inch equivalents due to lower production volumes.
Yes — standard NEMA hole patterns across all PRT caster sizes.
Effectively unlimited under normal service. Bearing wear is the typical end-of-life condition.
